It doesn't sound especially weird to me and I'm not French.

It's just "[create an] int [out] of [a] string"

"from" would have made more sense.

The words in brackets are doing all of the heavy lifting in your example though: "Of" without "out of" means "constituted by". If in isolation I saw "array_of_string" I'd definitely parse that as somehow being about str[], not "f(str) -> char[]"
